Embodiment 1

[0038] A novel plant drought-resistant yield-increasing agent, described drought-resistant yield-increasing agent is agmatine, and its specific application scheme is as follows:

[0039] (1) Select the drought-resistant wheat "Jimai 379 seeds" harvested in the same year with full grains and the same size, put them in a square box of 15cm*15cm*5cm, and cultivate them under constant temperature and light at a temperature of 22°C, 16 hours of sunshine and 8 hours of darkness Germinate and grow in the box for 7 days;

[0040] (2) Pick 10 wheat seedlings with the same growth state and size and place them at a height of 200 cm 3 liquid culture in a transparent plastic box;

[0041] (3) Drought stress on wheat seedlings: use 20% g / mL PEG8000 solution to carry out drought stress on wheat seedlings;

[0042] For specific operation steps, please refer to the papers published by the inventors: Yong-Bo Li, De-Zhou Cui, Xin-XiaSui, Chen Huang, Cheng-Yan Huang, Qing-Qi Fan, and Xiu-Sheng ...

Abstract

The invention belongs to the field of agricultural biology, and relates to a novel plant drought-resistant yield-increasing agent. The novel plant drought-resistant yield-increasing agent is agmatine; a plant drought environment is simulated to enable a plant to be in a drought stress state, then the agmatine is sprayed on the plant to prolong the green period of the plant; and the purpose of increasing the yield of the plant is achieved by maintaining the normal photosynthesis under the drought stress. Results show that the agmatine can inhibit wheat aging by improving the drought resistance of wheat under drought stress and increase the fresh weight of the plants, so that the biological yield of the wheat is improved; and the agmatine can be widely applied to drought resistance and yield increase of plants such as food crops, commercial crops and garden crops as a novel plant drought-resistant yield-increasing agent.

Description

technical field [0001] The invention belongs to the field of agricultural biology and relates to a novel plant drought-resistant and yield-increasing agent. Background technique [0002] Due to abnormal global climate change and severe shortage of water resources, plants are increasingly affected by drought stress. Affected by drought stress, plant leaves often wilt, resulting in a decrease in photosynthetic efficiency, which in turn affects plant yield. How to delay the leaf wilting of plants under drought stress, prolong the green period of leaves, so as to better maintain the normal photosynthesis of leaves, thereby reducing the losses caused by drought stress, and then increasing the yield of plants, it is urgent to find new methods for plant drought resistance and increase production . [0003] At present, the commonly used drought-resistance agent in production is 24-epibrassinolactone S-abensin, but its effect is not obvious. Therefore, whether to find a drought-re...
